Equipment Performance Influence on the Running Strategy of Residential Micro-cogeneration System

摘要：

Recently, residential micro-cogeneration is a growing interest energy system to reduce primary energy consumption and greenhouse gas emission in residential sector. However, the lack of decision on the reasonable operation strategy is one of important barriers to gain potential energy saving and environmental effect merits of cogeneration system. This paper analyzed the influence of micro-cogeneration equipments efficiency on the running strategy for residential micro-cogeneration system through discussing the introduction effect of a hypothetical microcogeneration system for a typical Japanese detached house. Based on the seasonally electricity and thermal load characteristics, several annual running strategies were discussed. By simulating hourly operation condition, the yearly energy consumption, CO2 emission and energy cost were calculated. Then, the energy saving, energy cost and environmental effects of running strategies in different electricity generation and thermal recover efficiencies were analyzed. These analysis results show that the optimal running strategy is different for different cogeneration equipments efficiency, and then the running strategy design should considering not only energy demand but also the equipments efficiency performance for residential micro-cogeneration system.
